SELF-FILLING FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Feb. 5, 191.

Application filed October 28. 1916. Serial No. 128,276.

To all whom it may concern:

Be it known that 1, WILLIAM K. BUoKLEs, a citizen of the United States, residing at Rifle, in the county of Garfield and State of Colorado, have invented certain new and useful Improvements in Self-Filling Fountain-Pens, of which the following is a speci fication, reference being had to the accompanying drawings.

This invention relates to certain improvements in self-filling fountain pens and is an improvement on the invention as embodied in my prior Patent No. 1,181,430 dated May 2, 1916; and it is an object of the invention to provide a pen having novel and improved means wherein a blade associated with a collapsible reservoir may be readily and conveniently operated in order to effect a filling of the pen.

The invention consists in the details of construction and in the combination and arrangement of the several arts of my improved pen whereby certaln important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view partly in elevation and partly in section illustrating a self-filling fountain pen constructed in accordance with an embodiment of my invention;

Fig. 2 is also a view partly in elevation and partly in section illustrating a pen constructed in accordance with my invention as herein disclosed; the line of section being substantially at right angles to the line of section of Fig. 1;

Fig. 3 is a transverse sectional view taken through the barrel of my improved fountain pen and looking toward the closed end or cap thereof;

Fig. 4 is a sectional View taken substantially on the line 1-4 of Fig. 1;

Fig. 5 is a view in bottom plan of the operating disk or button as herein employed; and

Fig. 6 is a view in top lan of the clamp-* ing member-herein inclu ed, detached.

As disclosed in the accompanyin drawings, 1 denotes the barrel of my improved fountaln pen which supports or carries in any desired manner the usual pen stock or nozzle 2 which in turns is provided with a passage 3 for the writing fluid. The passage 3 communicates with the pen 4 and the feeder bar 5 in the usual way, and the up per or inner end of the stock or nozzle 2 is provided with a reduced portion or neck 6 to which the compressible reservoir 7 is connected, said reservoir 7 being preferably formed of rubber.

As herein embodied, the lower or open end of the reservoir 7 is stretched over the reduced portion or neck 6 thereby holding ltself in applied position by the elasticity of the rubber. To further assure the connection between the reduced portion or neck 6 and the reservoir 7, T find it of advantage to employ the metallic ring or band 8 initially of a diameter in excess of the diameter of the neck or portion 6 and the encircling portion of the reservoir 7 and which is crimped transversely, as at 9, to assure the requisite clamping action upon the neck or reduced portion 6 and the coacting portion of the reservoir 7.

The crimped portion 9 of the band 8 also affords a socket or opening 10 to receive the extension or pintle ll arranged at the lower or inner end of the plate or shoe 12 adjacent one longitudinal margin thereof. The shoe or plate 12 is substantially flat and co-extensive with the reservoir 7 throughout the length thereof, and the upper or outer end of the plate or shoe 12 in longitndinal alinement with the extension or pintle 11 is provided with a second extension or pintle 14 adapted to be seated within a recess or cavity 15 formed in the under face of the cap or head 16 at the upper or outer end of the barrel 1.

The head 16 is provided with an arcuate slot 17 through which extends the finger or extension 18 disposed outwardly from the upper or outer end of the free longitudinal margin of the plate or shoe 12.

The extension or finger 18 is of such a length as to extend beyond the outer face of the cap or head 16 and extends within a radial slot 19 formed in the under surface of the disk or button 20. The disk or button 20 is rotatably engaged, as at 21, with the outer face or surface of the head or cap 16 whereby it will be perceived that upon rotating said disk or button 20 clockwise, the

plate or shoe 12 will be caused to collapse the reservoir 7 whereby a partial vacuum is caused so that when the reservoir is allowed to expand, the pressure of the outside atmosphere will force ink within the reservoir. It is also to be noted that the button co-acts directly with the plate or shoe 12 and as soon as said disk or'button 12 is.

moved the plate or shoe is actuated immediately. It is also to be noted that the disk or button 20 is held against movement longitudinally of the barrel 1 and rotated.

From the foregoing description, it is thought to be obvlous that a fountain pen constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some 'change and modification without material a departure from .the principle and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formationpf the Y several parts herein shown 1n carrying out my invention in practice, except as hereinafter claimed.

I claim:

In a self-filling fountain pen, the combination with a barrel having one and closed, said closed end being provided with an arcuate slot and a collapsible reservoir therein, a plate associated with the reservoir and mounted for rocking movement, said plate being provided with a finger extending exteriorly of the barrel through the slot in the closed end of the barrel, and a member positioned exteriorly of the barrel, said member being held against movement longitudinally of the barrel and rotatably supported by the closed end of the barrel, the inner face of said member being provided with a radial slot into which extends the finger of the plate whereby rotation of the member in one direction serves to move the plate toward the reservoir to collapse the same.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
